4100E 2.4G 4-Channel 4 Channels Micro Receiver for JR/SPEKTRUM DSM2 Transmitter

These are great little receivers. No problems whatsoever. I am wondering if the users who said they will not bind were binding it properly. The way the pins are, it’s very easy to miss a pin so that things are not plugged in correctly. I had trouble binding until I realized I did not have all the plugs in place correctly. Fix that mistake, and they work great. For me, just as good as more expensive receivers. I could not find any instructions, but had no trouble because they bind just like any other spectrum receiver. So these might not be the best receiver for a novice who doesn’t understand how to use them

As others have noted, there’s no documentation included. The negative pins are furthest from the board. If connected incorrectly, the LED just “blips”, connected correctly, the LED stays on. Bound to my very old Dx6i with no problem.

I purchased this receiver because it should have worked with my old spectrum DX3C transmitter that is DSM2. I tried to use it for a 1/24th scale LCG micro rock crawler build. It's a good size for 1/24th scale if it would work. It will bind to the spectrum DX3C transmitter no problem but no control functions. It seems like a hit or miss on this one. Seems to work great for some people and not for others. There's not much literature on this receiver but it seems pretty basic.

The first one I purchased would not bind to my transmitter. The replacement arrived within a few days and works as expected. The bind process was the same as the Spectrum brand receivers that use the bind plug. Bench testing shows that it works as advertised. I have not had a chance to fly it yet.

Like the size and works perfectly with my Spektrum iX12 transmitter. Would like to see channel labels but easy enough to figure out. Will purchase again for other small aircraft.

Works

Bound to my Spektrum NX6 transmitter no problem. Using it in a home built Great Planes airplane. As others mentioned there was no documentation but just followed the instructions that other reviewers have posted. I will buy it again in my next plane.

This is complete junk, do not buy. I checked out the supposed "bind instructions" posted on here by another user. 1st off, the picture shows the negative pin closest to the board. It will not light up when powered that way. I found that it lights up when the battery negative is plugged farthest from the board. When done this way the light comes on but does not flash. I tried it with the binding plug in the far left position just like the picture and it never flashes. Am I wrong? I will not bind to either one of my transmitters. EDIT- I tried it again, following the instruction and this time it worked. I still have not tried it in flight but it does work on the bench.

je l'utilise sur un bateau remorqueur a l'echelle et fonctionne tres bien avec ma spektrum dx9

No idea what the real range on them or anything Is but this is my go to for cheap rx that works with my dx7s have had no problems with them so far

It binds fine until you change the battery. So you can bind it, remove the bind plug and then fly. When you unplug the battery, it forgets and needs to be bound again to get a solid light.

Connected to Spektrum DX3 no problems, but didn’t realize it’s not for car/truck. Other than that it does work.

This reciever is lightweight and provides good range. Basic without bells or whistles which is exactly what I needed.
